TOOL HANDLE.

Application filed April 7, 1925.` Serial No. 21,292.

forms of hand tools having shanks or stem portons, which handle isadapted for use interchangeably with a variety of difierent forms oftools and also with various sizes of such tools.

A further object is to provide a handle which is readily applicable toand removable from the shanks or stem's of numerous tools, thus toprovide for the employment of a variety of such tools in connection witha single handle, with the ultimate end in view to measureably reduce theinitial cost, or purchase price, by eliminating the need for a handle oneach such tool.

In describing the invention in detail, reference is herein had to theaccompanying drawings, in which- Figure 1 is a side elevation of theinvention applied to the shank of a screw driver;

Figure 2 is a longitudinal section of the same; and- Figure 3 is aninner end elevation of the cap.

Referring to said drawings, 1 indicates generally the main body portionof the handle, preferably made of wood, the same having therein an axlebore 2l for the reception of the metal shank or stem 3a of a tool 3,which may be any of various hand tools, or may be any of various sizesof said tools. Fitted stationarily upon the outer end of ""saidhandle 1is a metal cap 4; of which the base member 4a carries centrally of itsinner face an integral forwardly projecting cone 5 which is received ina counterbore 6 provided therefor inl the outer end of said handle 1.Said cone has therein a central tapered socket 7 of square or othernoncircular form adapted for the reception of a correspondinglyl shapedend portion 3b formed on the end of l the shanka of the tool. The conehas its open end provided With a plurality of short longitudinal slits 8which divide said end into a plurality of fingers 9 which are more orless resilient and which, in introducing the tapered end 3b of the toolin the socket, tend to spring outward to a slight extent, thus not onlyproviding for yielding, gripping, 01' binding engagement between thefingers and the tool, but also between said fingers and the walls of theconical counterbore adj acent to the inner end of the latter. VSaidfingers preferably have the inner faces of their terminal portonsbeveled, as shown at 10.

From the foregoing it will be understood that screw drivers of varioussizes, as well as other forms of tools, all having shanks or stemportons 3** of cylindrical or roundrod form of a size to snugly fit thebore 2 of the handle and having tapered ends 3b adapted to snugly fitthe socket 7 of the cone 5, may be used interchangeably with a singlehandle having the structure hereinafter described.

What is claimed ist 1. A tool handle comprising a body having therein anaxle bore for the reception of a tool shank of round-rod form andprovided at its outer end with a counterbore, a metal cap mounted uponthe outer end of said body and having an integral cone extending intosaid counterbore, said cone having therein a central tapered socket ofe.whereby rotation of said shank is prevented.

2. A tol'handle comprising a body having therein an axle bore for thereception of a tool shank of round-rod form and provided at its outerend with a counterbore of conical form, a metal cap fixed on the'outerend of said body and having an integral cone fitted in said counterbore,said cone having an axial socket of tapered non-circular form for thereception of a correspondingly shaped end of the tool shank and having apluralityv of slits in its inner end whereby is formed a plurality ofresilient fingers adapted to be sprung outward'into binding relation tothe body.

3. A tool handle designed for use interchangeably with a plurality oftools' having shanks of round-rod form, said handle comprising a bodyhaving an axle bore for the reception of such shanks and having a tionof said cap and Within said counte-- bore, said member having a1:a,}3eredb non.-

oircul'ar 'socket therenfor the rec'ep'ton of the correspondingly'shaped' I'e'ai' end'of the tool sha-nk, said member being sl'itted toform reslent fingers adapted, to be sprung o outWazro by: szud' endinto' bindin'g: relation to the tapered porton of said shank.

In testimony' whereof, I aflix my signature.VV o
